Alternator/generator/regulator problems of the 2013 Hyundai Santa Fe

Purchasing the Hyundai Santa Fe 2013 was the biggest mistake I made. Since purchasing the vehicle I have spent over 5k in repairs, towing, and car rentals. First I was made to believe if I change all the oil and did all updates to the filters my car would stop stalling and shutting down on me that didn't work. Then my car shut down on the highway with my kids in the car almost killing us on the highway. I was told it was the wastegate needed changing. Then it shut down on minutes I exit my home in delaware and I was told it was the alternator and the battery. I was terrified to get in that vehicle and so was my family I filed several corporate complaints over the 2 years I have been ignored and not offered help. I have ask Hyundai to repurchase the vehicle but refused so I had no choice but to take the vehicle back that was in June with the promise and guarantee the car was finally fixed and I was safe. In the end of July I was driving on the I 495 about 40 miles per hour on the highway in the middle lane all of the car just stops in busy traffic a large freight truck was behind me honking to move he almost crushed me he swerve to side barely missing I was beyond frightened cars was flying by shaking the car it was on the hottest day I had no ac and my asthma was flaring up. I beg Hyundai to pick there vehicle up I was denied I called my triple a and they got the car. Now I'm being told it's the engine it's due to a recall that they supposedly already had repaired. I am told it will take 2 months for the repairs and I'm paying for my own rental. Hyundai consumer affairs denied taking there car back. I cannot get in this vehicle again. They refuse to give me paperwork on the recent incident when the engine fail. I fear for my life and my safety I am in desperate need of help please.
